使用devstack安装magnum 博客分类： openstackqemu devstackopenstackqemu

在redhat6.5上建立个centos7的虚拟机，使用centos7安装带magnum的devstack

systemctl stop firewalld
systemctl disable firewalld
iptables -F
关闭selinux

qemu-img create -f qcow2 zhycentos.img 500G 
qemu-img amend -f qcow2 -o compat=0.10 zhycentos.img 
virsh define zhycentos.xml
virsh start zhycentos

其中zhycentos.xml

安装系统后
进入系统
dhclient获取ip
selinux,iptables关闭

yum update
yum install gcc gcc-c++
#不要乱yum乱七八糟的东西，会有版本冲突。
yum install -y git  # 安装git
cd /home
git clone https://github.com/openstack-dev/devstack.git 
 
cd /home/devstack/tools/    # devstack默认不能以root身份运行
./create-stack-user.sh      # 会创建一个stack用户
chown -R stack. /home/devstack

cd /home/devstack
cp /home/devstack/sample/local.conf .

修改local.conf为

[root@magnum devstack]# cat local.conf 
[[local|localrc]]
enable_plugin magnum https://github.com/openstack/magnum master

disable_service n-net
enable_service  q-svc
enable_service  q-agt
enable_service  q-dhcp
enable_service  q-l3
enable_service  q-meta
enable_service  tempest

HOST_IP=192.168.139.221
FIXED_RANGE=10.24.0.0/24
NETWORK_GATEWAY=10.24.0.1
LOGDAYS=2
LOGDIR=$DEST/logs

ADMIN_PASSWORD=haoning
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SREVICE_PASSWORD=$ADMIN_PASSWORD

[root@magnum devstack]# 

运行stack.sh
如果出现python的版本问题
sudo pip install <模块名>==<版本号>

简单测试

cd /home/devstack
source ./openrc admin admin

nova keypair-add --pub-key ~/.ssh/id_rsa.pub testkey
